What is an air purifier?
An air purifier or air cleaner is a device which removes contaminants from the air in a room. These devices are commonly used as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke.
How does an air purifier work?
Room air conditioner filters only capture particles 10.0 microns or larger. HEPA filters remove smaller allergens like dust, smoke, chemicals, asbestos, pollen, and pet dander. The more times the air passes through the HEPA filter, the cleaner the air becomes.
Can air purifiers remove dust?
Run an air purifier for dust. The best air purifier for dust on the market utilizes HEPA (High Efficiency Particulate Air) filters. Effective HEPA filters can remove up to 99.97% of airborne particles, helping you effectively control and reduce dust inside your home.
What are the benefits of an air purifier?
Air purifiers are appliances that aid in removing pollutants from air. They are very helpful devices for people who suffer from asthma or allergies. HEPA filters can clear the air of dust, pollen, pet dander, smoke and almost all pollutants present in the air.
The air outdoor is so polluted, how much of a difference can an indoor air purifier make?
On an average, we spend close to 80% of our time indoors (home, office, etc.) children and babies spend even more time indoors. With an air purifier, you can control the quality of air indoors and protect your family, and it is indoor air which is more polluted than outdoor air as per data sources.
Can you run the air purifier throughout the day?
You can. The power consumption is very low, so long usage doesn’t cause a heavy impact on electricity bill. As compared to an AC which consumes 2000w power, an air purifier consumes 1/40th of it (~50W). So power consumption per hour of an AC is equivalent to 40 hours of power consumption by an air purifier. The filter life is dependent on usage/quality of air and that should be kept in mind.
How long do the filters last?
Filter life is proportional to the pollutant holding capacity and the pollution level in your surroundings. TRUE HEPA filter has high capacity, thus the long filter life. A filter will last longer in a relatively cleaner area. In general , filters last for 12-18 months with 6-8 hours daily average usage.
Does CADR vary with fan speed?
CADR is specified for the highest speed setting. But users will often use lower settings to reduce noise, and this can reduce the efficiency of an air purifier.
What should be the required CADR for my room?
AHAM recommends a “two-thirds” rule when it comes to the first rating. “you will always want a unit with a tobacco smoke CADR at least two third your room’s area. Example if your room is 420 square feet in area, buy an air purifier with atleast a CADR of 2/3*420= 280m cube per hour.
Many air purifiers have a HEPA filter. How to differentiate?
There are a lot of air purifiers out there which are advertised as having HEPA filters, but actually don’t. Usually these are disguised as having HEPA-like filters, and don’t meet strict HEPA standards.
What other features may i look into before buying an air purifier?
Features like caster wheels, handles for easy mobility, digital controls, remote controls, timer settings, multiple fan speeds may be additional features which one can look for while buying air purifiers.
What are the differences between an air purifier and humidifier?
Air purifiers are used to clean indoor air, but do not optimize humidity levels. They remove particles, dust, and smoke from the air, as well as allergic substances like animal dander and pollen. Humidifiers increase the humidity level by distributing water into dry air.
I want cleaner air, so i will need an air purifier. However, i am still not sure if i should get a humidifier.
Dry air may cause chapped skin, contribute to respiratory problems, increase static electricity, and cause wooden furniture to crack. Humidifiers help to optimize the humidity level of indoor air to reduce the level of dryness in the air within your home.
I want the benefits of a humidifier, but my house does not have space for both appliances.
You may consider a 2-in-1 solution commonly known as a Combi; such an appliance combines the functions of an air purifier and a humidifier.
